Revert "powerpc/xmon: Relax frame size for clang"

Browse Source 
This reverts commit 9c87156cce.

I have not been able to reproduce the reported -Wframe-larger-than=
warning (or disassembly) with clang-11 or clang-18.

I don't know precisely when this was fixed in llvm, but it may be time
to revert this.
